    • The present invention provides a monitoring system enabling efficient determination of code amounts for respective cameras according to the movement of an object. Each camera (101) making up the monitoring system includes: a collaboration parameter updating unit (413) which updates a collaboration parameter, based on the position of the object detected by a sensor (106) and position identification information and collaboration parameter of a neighboring camera stored in a neighboring camera information storage unit (405), so that (i) a distribution pattern indicating the distribution of the collaboration parameter value in a space where plural cameras are present forms a concentric circle with the object being the origin, and (ii) the target code amount for a camera capturing the object becomes larger than that of a camera not capturing the object; and a target code amount determining unit (410) which determines the target code amount assigned to the camera based on the updated collaboration parameter, and the collaboration parameter and the target code amount for the neighboring camera stored in the neighboring camera information storage unit (405).
    • 本发明提供了一种能够根据对象的移动有效地确定各个照相机的代码量的监视系统。 构成监视系统的各照相机(101)包括:基于由传感器(106)检测到的物体的位置和相邻的位置识别信息和协作参数来更新协作参数的协作参数更新单元(413) 存储在相邻相机信息存储单元(405)中的相机的相机,使得(i)指示在存在多个相机的空间中协作参数值的分布的分布模式形成以对象为原点的同心圆,并且( ii)拍摄对象的相机的目标代码量比不捕获对象的相机的目标代码量变大; 以及目标代码量确定单元(410),其基于更新的协作参数来确定分配给相机的目标代码量,以及存储在相邻相机信息存储单元(405)中的相邻相机的协作参数和目标代码量 )。
